We used to have cattle, and they got away quite a bit (not as much as the sheep we had one year, though.) Being about one and a half years old, I thought it was fun, the one time I remember them getting away, but my parents didn't like it. The cattle were better than the sheep in more than one way: the cattle always went up the hill on the road, but the sheep went anywhere they wanted when they excaped. So I'd say that if cow farming caused complaints, all farmers can complain. Anyway, if it rains too much, that's just as bad.
